SPECIFICATION forming part of Letters Patent No. 644,178, dated February 27, 1900. Application iiled May 31, 1898. Renewed .Tuly 28.1899. Serial No. 725,371. (No model.)

To @ZZ whom t may concern.- v

Be it known that I, DRURY T. KIRKPATRICK, of the city of Memphis, Shelby county, State of Tennessee, have invented certain new and useful Improvements in Vapor-Burners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to vapor-burners; and 1o it consists of the novel construction, combination, and arrangement of parts hereinafter' shown, described, and claimed.

Figure 1 isv a vertical sectional view taken through the fire-box of a stove provided with i5 my improved vapor-burner. Fig. 2 is an enlarged elevation of the burner, parts thereof being in section to more clearly illustrate the same.

Referring by numerals to the accompanyzo ing drawings, l indicates the body of astove,

2 the fire-box thereof, and 3 the grate.

Located upon the grate is a sheet-metal plate 4, provided in its center with an opening 5. This plate is not essential,thou gh by its use the z 5 efficiency of the burner is greatly increased. Located upon the floor, or upon the Wall, or at any point adjacent to the stove is an oiltank 6, which is provided with an ordinary air-pump 7, the same providing means where- ;o by air under pressure may be forced into said tank 6, said tank 6 also being provided with an inlet-opening 8, the same being normally closed bya cap.

Leading from the lower end of the tank 6 3 5 is an oil-conveying pipe 9, in which is located an ordinary cut-off valve 10, the end of said pipe 9 being connected by an elbow to a horizontally-arranged length of pipe 11, in which is located a check-valve 12, said pipe 11 ex- 4o tending horizontally into the re-box 2 of the stove, and in the length of said pipe 11 is formed a coil 12', which when the burner is properly positioned Aoccupies a central location Within said lire-box. The free end of this pipe 11 is tapped into the lower end of a vertically-arranged gas-conveying cylinder 13, in'

which is formed a vertical bore 14, closed at its lower end by a plug 15.

The vapor-superheating chamber is con- 5o structed of an enlarged horizontally-arranged tube 16, having both ends closed by screwfrom the opposite end of said chamber is a tube 19, the same being connected by an ordinary elbow to a short vertical tube 20, the lower end of which is connected by an elbow to a horizontally-arranged tube 21, that extends beneath the tube 11 to a point immediately beneath the coil 12 therein, and said tube 21 is there connected by an ordinary elbow to a short vertical tube 22, that extends upwardly through the coil 12' and is provided with a burner-cap 23, in the top of which is located a suitable aperture.

By referring further to the drawings it will be seen that the cap 23, or the upper end of the burner, extends above the coil 12 and that the latter operates to hold the vertical tube 22 of said burner in a true vertical position, whereby the flame will only come in contact with the horizontal tube 16, forming the superheating-chamber, the latter further operating to spread and vdivide the flame on either side of the same.`

Vhen the various parts of my improved burner have been assembled and are in proper position relative to a stove and it is desired t0 operate said burner to heat the stove, the

pressure is pumped up yvithin the tank 6 by means of the air-pump 7, and when this operation is completed and the cut-od valve l0 is opened oil will be forced upwardly through the tube 9,through the check-valve 12,through the tube 11, upwardly through the body of the cylinder 13, through the tubes 18, 16, 19, 20, and 21, and as the oil appears through the aperture in the burner-cap 13 said oil is ignited,'or, if desired, a small section of asbestos paper may be located upon the plate 4, immediately beneath the burner-cap 23 and short section of pipe 22, and afterthe oil drops downwardly onto said asbestos paper and saturates the same it may be ignited, and in this manner the burner-cap 23 and coil 12 will become heated, and as the oil continues to flow through the tubes 19 and 11 it will pass into the heated coil 12' and be thereby formed into a vapor, which vapor will pass onwardly through the pipe 11 to the cylinder 13, from IOO thence through the tube 18 and into the tube 16, forming the vapor-superheating chamber, and here said vapor will be superheated, and as it does so it will expand and pass onwardly through the tubes 19, 20, 21, and 22 and discharge through the burner-cap 23, where it is ignited. The iame thus produced strikes against the tube 16, forming the vapor-superheating chamber, and very thoroughly heats the same to superheat the vapor formed in the coil 12', and at the same time all of the pyrites and paraffin-Wax that may be in the oil are thoroughly consumed, and consequently there will be nothing discharged through the aperture in the burner-cap which will tend to clog the same.

The check-valve 12 allows the oil to pass freely through the tube 1l toward the coil l2 and effectually prevents any oil or vapor from passing backwardly through the Said tube 11.

By providing a pressure Within the tank 6 the oil is forced into the vapor-forming coil continuously and evenly, and therefore the burner will produce a flame that will create an even temperature within the stove and all parts thereof.

A burner so constructed is simple, strong, and durable, readily applied to any heating or cooking stove, occupies very little space Within and adjacent a stove, is very economical in the consumption of oil, is very safe, and comes Within the provisions and regulations made by insurance companies, and by superheating the Vapor a much greater heat is produced and there is no danger of the aperture in the burner ever becoming clogged.

I claim- A vapor burner comprising an enlarged horizontally-arranged superheating-chamber, an oil-supply pipe in connection with one end of the same, a coil formed in said pipe, a burner passing through the coil and extending above the same, suitable pipe connections leading from the opposite end of the superheating-chamber to the burner, whereby the latter is held in a vertical position to cause the flame issuing from the upper end of the same to come in contact with the superheating-chamber located above the burner, and a check-valve located in the oil-supply pipe, substantially as and for the purpose dcscribed.

In testimony whereof I affix my signature in presence of two witnesses.

DRURY T. KIRKPATRICK.
